[0021] Embodiment 1:

[0022] Referring to Figures 1 - 4 , a primary-secondary integrated pole-mounted circuit breaker that is convenient for installation, comprising a circuit breaker main body 20, a vacuum interrupter 21 is provided at the top of the circuit breaker main body 20, an installation frame 10 is connected below the circuit breaker main body 20, a rectangular cut 11 is formed on one side surface of the installation frame 10, the circuit breaker main body 20 is placed in the rectangular cut 11, cut grooves 12 are symmetrically provided on one side of the rectangular cut 11, and positioning shafts 22 are symmetrically provided on one side of the circuit breaker main body 20;

[0023] In the above technical solution, the installation frame 10 is used to support and place the circuit breaker main body 20. When installing the circuit breaker main body 20, the circuit breaker main body 20 is placed from above the installation frame 10, and the circuit breaker main body 20 enters the rectangular cut 11 for positioning. At this time, the left and right directions of the circuit breaker main body 20 are restricted by the rectangular cut 11; and the symmetrically arranged positioning shafts 22 slide into the cut grooves 12. The bottom of the cut groove 12 is in a semi-circular arc structure that just matches the size of the positioning shafts 22. At this time, the front and back directions of the circuit breaker main body 20 are restricted by the cut grooves 12. The design of placing the circuit breaker main body 20 from above makes the installation process more intuitive and simple, which is conducive to the cooperation between the positioning shafts 22 and the cut grooves 12. The operator can quickly place the circuit breaker main body in the correct position without complex adjustment or alignment steps, thereby improving work efficiency and installation speed. A stable installation foundation helps to reduce the shaking or deviation of the circuit breaker main body during operation, thereby improving the overall stability and safety of the equipment.

[0024] Furthermore, side ears 25 are installed on both sides of the installation frame 10. Bolts are installed on the side ears 25 to position and stably install the installation frame 10.

[0025] Referring to Figure 3 and Figure 4The surface of the mounting frame 10 is symmetrically provided with hinge plates 13 near the rectangular cutout 11, and a positioning member 14 is rotatably connected to the hinge plates 13. The positioning member 14 comprises a large arm 15, a corner arm 16 and a positioning arm 17, wherein the large arm 15 is rotatably connected to the hinge plate 13, the large arm 15 and the corner arm 16 are at a right angle, the positioning arm 17 is provided on one side of the corner arm 16, and a fitting disk 23 is provided on one side of the positioning shaft 22, wherein the outer side of the fitting disk 23 is fitted on the inner side of the positioning arm 17, and a threaded hole 26 is provided on the surface of the fitting disk 23 to enter the positioning shaft 22, and a screw 24 is engaged with the inner thread of the threaded hole 26.

[0026] In the above solution, when installing the circuit breaker body 20, the positioning member 14 needs to be rotated first. Figure 2 As shown, after the circuit breaker body 20 is installed stably, the positioning member 14 is reset as shown in FIG. Figure 1 and Figure 2 As shown, at this time, the screw rod 24 passes through the positioning arm 17 and enters the threaded hole 26, so as to limit the displacement direction of the upper part of the circuit breaker body 20, so that even if shaking occurs, the circuit breaker body 20 will not be separated from the installation frame 10, further improving the stable installation effect of the circuit breaker body 20. At the same time, to remove, replace or maintain the circuit breaker body 20, it is only necessary to remove the screw rod 24 in the threaded hole 26, and then rotate the positioning member 14 to make the upper part of the corner arm 16 separate from the upper part of the circuit breaker body 20, and then lift it up or hang it up for simple replacement and maintenance of the circuit breaker body 20.

[0027] In summary, the positioning shaft 22 cooperates with the cutout groove 12 to restrict the front-to-back direction of the circuit breaker body 20, and the threaded hole 26 in the positioning shaft 22 cooperates with the screw rod 24 to restrict the upper displacement direction of the circuit breaker body 20. The circuit breaker body can be quickly disassembled and installed by only removing or installing the screw rods and the extrusion rods at two locations, simplifying the installation and disassembly steps.

[0028] Furthermore, the positioning arm 17 is made of rubber material. The positioning arm 17 is made of rubber material so that the positioning arm 17 has toughness, and the position of the positioning arm 17 can be adjusted finely, so that the positioning arm 17 is conveniently positioned next to the laminating plate 23 .

[0029] Further references Figure 1 and Figure 4 The corner arm 16 is threadedly engaged with an extrusion rod 18, and a rotating handle 19 is provided above the extrusion rod 18. After the screw 24 is installed, the extrusion rod 18 is rotated synchronously, and the bottom of the extrusion rod 18 is pressed on the top of the circuit breaker body 20 to further improve the stability of the circuit breaker body 20. The rotating handle 19 facilitates the rotation of the extrusion rod 18 under force.

[0030] The specific implementation process of this embodiment is as follows:

[0031] When disassembling the circuit breaker main body 20: Rotate the extrusion rod 18 so that the extrusion rod 18 disengages from above the circuit breaker main body 20. When removing the screw 24 and rotating the positioning member 14 to disengage the upper part of the corner arm 16 from above the circuit breaker main body 20, the circuit breaker main body 20 can be lifted upward or hoisted to facilitate replacement and maintenance of the circuit breaker main body 20.

[0032] While the positioning shaft 22 cooperates with the notch groove 12 and the front-rear direction of the circuit breaker main body 20 is restricted, the threaded hole 26 in the positioning shaft 22 cooperates with the screw 24 to restrict the upward displacement direction of the circuit breaker main body 20. Only by removing or installing the screws 24 and the extrusion rod 18 at two places can the disassembly and installation of the circuit breaker main body be quickly realized, simplifying the installation and disassembly steps.
